Do Gemini girls are really that happy or strong?

 I am a Gemini girl, a typical one. After having almost 22 years of my life, I gradually become mature with many experiences and lessons.
    In others' eyes, including the classmates and also the strangers, I should be a very active, outgoing, positive, happy girl, who likes to talk to people all the time, who likes to smile all the time, who is very good at her study or job all the time. However, I have to admit, I'm not!
    Recently, this is happening again. One of my primary school classmates contacts me and began to call me and talk with me about his business thing everyday. It seems he really misses the past times when all of us are very innocent. I would sometimes encourage him and help him solve some puzzles. Through him, I surprisingly found that I would usually act as a senior person who would like to comfort others and encourage others. Of course, he thinks I'm a girl who should be like a girl with the above descriptions.
    At first I was a little bit frustrated, cause I can't be that strong as you think, I also would cry when I meet with difficulties, I also would be upset and don't want to talk to anyone sometimes,I also have my own problems.
    But then I came to realise that it is on me. It is me who won't tell others that you are weak now, it is me who won't say no when someone's asking. I gave others the illusion. I know I should take responsibility!
    However, actually, I'm not as strong as others think.I just want to do my best to help others.
    I would still be a girl who would show her smile every day to others;I would still be the girl who would like to encourage others even though I myself are not that happy right now. Because I always believe that the more we help others, the happier you will be, and a better world we can creat!
